SILVER FIRS. 205 



stiff, and acute. Seeds triangular and soft, with broad wings. 

 Seed-leaves in fives. 



A tall tree, with the appearance of the common Silver Fir 

 found, according to Dr. Siebold, on the Japan Islands of 

 Nippon, and Jezo, and frequent in the provinces of Matsu and 

 Dewa, at an elevation of 2000 or 3000 feet. The Japanese dis- 

 tinguish different varieties under the names of" To-Momi," from 

 the north of China, and the " Jezo-Momi," or the "Nire-Momi," 

 of Japan ; this last is distinguished by its leaves sloping more 

 towards the ends of the branches, and by the cones being much 

 shorter. They also distinguish a kind with the ends of the 

 leaves deeply divided (bifid) ; but such variations appear to be 

 produced by elevation, climate, and soil, and are, as well as Dr. 

 Siebold's Abies homolepis, nothing but the species altered by 

 such circumstances. In Japan it is called " Uro-Siro" (leaves 

 white beneath), and "Sjura-Momi" (white, or Silver Fir).
